Mangled bundles are what you get when you process mangled hides (1 for 1) on a refining table. The refining recipe may not be available till level 4 or so - if things haven't changed, the recipes a trainer has for you should be visible even if you're not high enough level to train them.

Remember that there are two basic processes in crafting, refining and finishing. (Apologies for the reiteration if you already knew this.)

Note also that the Jute Cloth ... bundle? whatever it's called - that you can make will require the same refining table and Jute Bales made from harvested Jute sheaves.

Now, if you knew all of this and *still* can't see the recipes you need, and they aren't available to train, then there may still be a bug. It was there at the end of beta and though they were officially squished, you know bugs... they'll still be there at the end of the world.
